There are several potential reasons why a 5-year-old Whirlpool double-door refrigerator might intermittently stop making ice. Some common issues to consider include:
Water Supply Problem: Check if the refrigerator is receiving a continuous water supply. If there is a problem with the water inlet valve or the water line, the ice maker might not get enough water to produce ice consistently.
Clogged Water Filter: A clogged water filter can restrict water flow to the ice maker. If the filter hasn't been replaced in a while, it might be time to do so.
Ice Maker Components: Over time, certain components of the ice maker can wear out or get damaged, leading to inconsistent ice production. The ice maker module, motor, or mold heater could be causing the issue.
Temperature Issues: The ice maker's performance can be affected by temperature fluctuations. If the freezer compartment is too warm, it might not freeze the ice properly. Check the freezer temperature settings and ensure they are at the recommended level.
Ice Maker Switch or Sensor: The ice maker's on-off switch or sensor might be faulty, causing it to stop working intermittently. Check for any loose connections or signs of damage.
Ice Bin Position: You mentioned that the metal switch inside the bin is in the proper position, but it's essential to double-check if it's making proper contact. Sometimes, the switch may not engage correctly, causing the ice maker to think the bin is full, leading to a temporary halt in ice production.
Electronic Control Board: The electronic control board that governs the ice maker's operation could be malfunctioning. If the control board is faulty, it can cause irregular ice production.
To diagnose the issue accurately and safely, it's best to contact a qualified appliance repair technician. They will be able to inspect the refrigerator, check for error codes, and perform tests to identify the specific problem. Attempting to repair the refrigerator yourself could lead to further damage or void the warranty if it's still covered.
If the refrigerator is still under warranty, you may want to reach out to Whirlpool's customer support to inquire about repair options or authorized service centers in your area.
